Being a scuba diver, it’s all about gearing up for an adventure beneath the waves with a buddy you wouldn't want to dive without – a nitrox analyzer. It's like your underwater safety guide, ensuring you know exactly what you're breathing in from your dive tank. These analyzers measure the oxygen concentration in a dive tank, providing divers with accurate information to plan safe dive profiles. This isn't just about safety; it's about making your dive as enjoyable as possible.


Nitrox analyzers are an invaluable tool for any diver using enriched air—whether you're a seasoned veteran or just starting. At Dive Right in Scuba, we've curated a selection of high-quality nitrox analyzers designed to meet the needs of our customers. By ensuring that our diving gear aligns with the highest standards of safety and performance, we can confidently say that we have taken a step towards smarter and more enjoyable diving endeavors.

Features and Specifications

A nitrox analyzer is an essential tool for scuba divers, particularly those who dive with enriched air nitrox (EANx). Since the percentage of oxygen in nitrox blends can significantly affect no-decompression limits, partial pressures, and the risk of oxygen toxicity, divers must verify the blend before diving.

When we consider Nitrox analyzers, we focus on attributes that ensure accuracy, ease of use, and reliable performance. Dive Right in Scuba understands the importance of these features, enabling divers to measure oxygen levels with confidence.

Light Weight and Compact Design

The design of a Nitrox analyzer is pivotal to its operation. The weight and dimensions are critical; a lightweight analyzer is always a plus.

When it comes to build quality, we choose models constructed with materials known for their longevity and resilience to temperature and humidity fluctuations.

LCD Display

An LCD or digital display is a must for clear readability. We value screens that show us essential information at a glance, under any diving conditions.

User Interface

The user interface is equally crucial. We prefer analyzers with intuitive controls that facilitate easy operation, even when wearing gloves. Additionally, features like a flow limiter can help us achieve precise readings.

Long Battery Life

As for power, a long battery life is a significant advantage, ensuring our analyzers are ready for use whenever we need them.

Advanced Usage and Connectivity

Our Nitrox Analyzers, designed for recreational and technical divers, now offer sophisticated integrations and smart device applications that set them apart in the diving industry.

Integrations with Diving Equipment

Modern Nitrox Analyzers are not just standalone devices; they seamlessly integrate with diving equipment to allow for a more holistic approach to dive safety. Our analyzers boast Bluetooth capabilities, enabling a wireless connection directly to both BDCs and rebreathers, facilitating real-time monitoring of your gas mix. This ensures that you are always informed and confident about the quality of the gas you breathe.

Accessories and Compatibility

When outfitting your diving gear with a Nitrox Analyzer, it's essential to consider the appropriate accessories for optimal functionality and ease of use. At Dive Right in Scuba, We've curated a selection that ensures durability, proper flow rate, and compatibility with your devices.

Adapters and Hoses

For a Nitrox Analyzer, the connection is key. We provide Divesoft hoses that are designed to be both durable and flexible. These hoses include options like the quick disconnect (QD) low-pressure (LP) hose, that offers easy attachment and detachment, regulating a consistent flow rate for accurate readings.

Operational Aspects

Before diving into the specifics, it's essential for nitrox divers to understand that an accurate nitrox analysis hinges on proper calibration and regular maintenance of their nitrox analyzer. Here at Dive Right in Scuba, we ensure our products are reliable and user-friendly.

Calibration Procedures

To ensure that the nitrox analyzer gives precise readings, regular calibration is a must. It's a straightforward process:

  1. Access ambient air with a known oxygen percentage (20.9% O2).
  2. Attach the analyzer to the pressure valve on the tank.
  3. Use the calibration function to set the device to 100% oxygen when a pure oxygen source is used, or to ambient air percentage for calibration at atmospheric conditions.

Calibration should be done before each use, particularly when you switch between tanks or if the analyzer has not been used for an extended period. Recording the calibration date ensures you maintain a reliable log of your equipment's status.

Maintenance and Sensor Replacement

Maintaining your nitrox analyzer is crucial for its longevity and accuracy. Consider the expected sensor life and remember to check the response time during maintenance checks.

  1. Clean the sensor and replace protective caps when not in use.
  2. Sensor life varies but is generally around 36 months with proper care.
  3. Schedule annual sensor replacement to mitigate unexpected failures. A proactive approach avoids issues before extensive use.

Note: Some models provide resolution characteristics such as +/-1% accuracy, which could differ based on the sensor type and age. Always refer to your specific model's manual for optimized maintenance.

Frequently Asked Questions

What are the main features to look for in a scuba oxygen analyzer?

When shopping for a scuba oxygen analyzer, we recommend focusing on accuracy, ease of calibration, a user-friendly interface, durability, and the ability to measure a wide range of oxygen concentrations. Features like a long battery life and a clear display are also significant to consider.

How do you accurately use a portable oxygen analyzer for scuba diving?

To use a portable oxygen analyzer accurately, we advise calibrating it with a known gas mixture, such as air, before each use. Ensuring a consistent flow rate over the sensor is crucial for reliable readings. Each model may have different methods for maintaining the flow.

What is the price range for a reliable nitrox analyzer?

A reliable nitrox analyzer can vary in price, typically ranging from around $200 to over $400. The cost depends on the features, brand, and quality of the device. It's a worthy investment for any diver regularly using enriched air nitrox.
